I want to collect % CPU load of each Redhat host in network.So,How do I record/get this this information on to a host in network.Is there any shell script to run Linux commands to achieve this?. Or else I need to configure openssh first.Is there any other way instead oppenssh? I want to store %cpu load of each host into separate variables.
Please help....

Without details, no one will be able to help you. What do you mean by "node"? What OS are those nodes running? How often do you want this to update? What are you feeding those results IN to? How are they going to be displayed? What's your goal???

There are many monitoring utilities/systems for Linux...Zabbix and Nagios are two, and provide this functionality for any monitored system. Running the "top" command will also give you that data, as would an snmp query. Google has THOUSANDS of examples of all of the mentioned methods...since you don't say what your goals are or what you're trying to do, that's the best place for you to start.
